Abstract

La présente invention concerne un appareil et un procédé destinés à interrompre le courant dans un circuit. La pression magnétique induite par le passage du courant à travers un conducteur amène le conducteur à s'écouler, d'où l'ouverture du circuit associé. La pression magnétique peut être dérivée d'équations de Lorenz. Ainsi, la pesanteur n'est pas nécessaire pour amener le matériau conducteur à s'écouler. Cette invention peut être utilisée dans des circuits présentant des courants élevés par rapport à la sélection de la taille et du matériau du conducteur.
